1日粮中添加过瘤胃保护B族维生素对奶牛健康、产奶量和繁殖性能的影响显示文摘围产期日粮中添加过瘤胃保护B族维生素对奶牛健康、产奶量和繁殖性能都会产生影响。试验结果表明,添加过瘤胃保护B族维生素可以显著降低刚分娩奶牛亚临床酮病的发病率、奶牛平均人工授精成本以及泌乳190天内的淘汰率(P<0.05);显著增加乳脂率和泌乳150天怀孕率(P<0.05);胎衣不下的发病率从18.5%减少到16.0%,但是差异不显著。这说明在围产期日粮中添加过瘤胃保护B族维生素可以提高牛奶乳脂率、奶牛健康状况以及繁殖性能,并能为奶牛场节省成本,提高经济效益。Essi Evan Helene Leclerc Stacy Wrinkle 詹小立 阳成波 2015中国乳业2015,,8:2
2Review: Sugar beets as a substitute for grain for lactating dairy cattle显示文摘Dairy cows are customarily given grains and highly digestible byproduct ingredients as additions to forage to support milk production. In many parts of the world growing seasons are short, and the grain crops that can be grown may not provide adequate yields. Sugar beets, on the other hand are relatively hardy, and dry matter yields surpass the yields of most grain crops. There are however, perceptions that beets may not be suitable as a feed ingredient due to the fact that the storage form of carbohydrate is sugar rather than starch. With little analytical support, sugar has been rejected in many feeding programs with the view that sugar reduces rumen pH, fiber digestion and microbial yield. This review explores available facts revolving around these concerns. Information regarding the feeding of sugar beets is provided and the use of sugar beets as a partial replacement for grain is proposed.Essi Evans Ulrike Messerschmidt 2017Journal of Animal Science and Biotechnology2017,8,3:2
